DOYLESTOWN, Pa. (CBS) — Prosecutors in Bucks County say a 21-year-old Doylestown man will now face homicide charges after the man he allegedly stabbed last week near the Doylestown train station died over the weekend.

Authorities confirm that 71-year-old George Mohr passed away Saturday night at Temple University Hospital.

Mohr, whose last known address was in Phoenix, Ariz., was stabbed more than 70 times early in the morning last Wednesday (See Related Story).

Prosecutors say the suspect, 21-year-old Dale Wakefield of South Clinton Street in Doylestown, had initially been charged with attempted murder, but those charges will now be elevated.

According to officials, Wakefield fled to Maryland after the murder and is now being held in a Baltimore jail. Prosecutors say they will begin extradition proceedings if he does not voluntarily return.

Authorities say a motive for the stabbing is unclear. Mohr was a US Army veteran.
